Deprecated.
This internal logback API is not supported by AEM as a Cloud Service.
This appender and derived classes, log events asynchronously. In order to avoid loss of logging events, this appender should be closed. It is the user's responsibility to close appenders, typically at the end of the application lifecycle.

This appender buffers events in a BlockingQueue. AsyncAppenderBase<E>.ch.qos.logback.core.AsyncAppenderBase.Worker thread created by this appender takes events from the head of the queue, and dispatches them to the single appender attached to this appender.

Please refer to the logback manual for further information about this appender.

1.0.4
